DAB (BS2000)

Sophisticated, scalable and self-adaptive caching technologies are fundamental for performant, self-optimising E-Business-applications with guaranteed response-times (Business Critical Computing). Caches accelerate the reading and writing of data by factors. They are applied in networks, servers and disk subsystems. DAB is the BS2000-software for disk data caching in main memories or/and in Global Storages of BS2000-Servers.

The Disk Access Buffer (DAB)

manages the caching of peripheral data on high-speed semiconductor memories

buffers the data in intermediate storage (caching) with far shorter access times than those possible for external data storage (disk storage)

can use various types of storage media (such as main memory (MM) and global storage (GS)) as buffers

supports main memories up to 2 Tbytes and files up to 4 Tbytes.

The advantages of DAB are apparent in both sequential processing and in very localized random-access processing. DAB also provides write caching for significant performance gains in applications with high write rates.
